I've enjoyed The Museum of Online Museums for years -- it's full of amazing collections of odd things. I even linked to one of the collections back in 2007. Now a three-part documentary called "The Curators" visits three curators of these museums and tells their stories. They're great fun -- these are collections any of us (at least any of us with a lot of time on our hands) could create. Recommended for fans of: museums, found objects, weird web stuff, libraries, photographs, and documentaries.

This one has an interesting bit (about halfway through) about how the collection was discovered, shedding light on a big mystery -- why were all these photos thrown away? Also check out the NPR story about the collection.
